Method and system for providing terminal security checking service

ABSTRACT

A terminal security checking service providing method and a system for the same are provided which are capable of updating information to be used as security measures even while the system is being shared among users. When one or more external media are connected to one or more terminals, information for security check is transferred to a security checking server. Security check results are transmitted through the one or more terminals, one or more external media, and an external medium initializing unit to the security checking server. Information to be used as security measure corresponding to the security check results is sent back from the security checking server through the external medium initializing unit to the one or more external media to initialize the one or more external media.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a method and a system for providing a terminal security checking service, and more particularly to the method and the system for providing the terminal security checking service, which are capable of achieving higher-level security and flexibility even while the system is shared among users and of increasing flexibility of the system.

The present application claims priority of Japanese Patent Application No. 2005-203562 filed on Jul. 12, 2005, which is hereby incorporated by reference.

2. Description of the Related Art

In recent years, the Internet has come into widespread use and enterprise networks are being constructed on the Internet, while Internet viruses make entries into terminal devices (hereinafter simply a “terminal”) for the enterprise networks and worm viruses cause a shutdown of such the enterprise networks, which has a significant effect on enterprise activities. To avoid such events, software that can make a check of entries of worm viruses or a security patch to be applied for a fix to security holes in an OS (Operating System) of a terminal and in application software, or a like are widely installed, however, daily thorough checking by using such security described above is becoming more difficult.

As a conventional security measure, a PC (Personal Computer) quarantine system is used which makes a security check when a terminal is connected to an enterprise network and provides, after completion of the security check of the terminal, information to be used as security measures (information about security protection) that can cover a weakness/a unreliability of a security measure already taken for the terminal, for example, a security patch. The conventional PC quarantine system is roughly classified under two types, one being a first-type system configured to have a server to provide terminal security checking service and a client software and the other being a second-type system configured to have a server to provide terminal security checking service and a clientless module. In the above first-type system, dedicated client software is installed on a terminal. In the above second-type system, no dedicated client software is installed on a terminal.

FIG. 10 is a diagram showing configurations of an example of the above conventional first-type PC quarantine system. The first-type PC quarantine system chiefly includes a terminal 100 installing security checking client software 111, a security checking server 200, and a network connection managing system 300. These components are connected to a network 400 constructed within a same corporate organization.

In the first-type PC quarantine system, when the terminal 100 is connected to the network 400, the security checking client software 111 collects information about an OS of the terminal 100, information about a version of virus checking software, or a like and transmits the information to the security checking server 200. The security checking server 200 checks, according to preset contents to be used for checking, whether or not a specified security patch is applied. Then, results from the security checking are transferred from the security checking server 200 to the network connection managing system 300. If the result from the security checking is OK, the terminal 100 is connected to the network 400 in an enterprise to perform ordinary processing tasks. However, if the result from the security checking is NG (not good), or shows an error, the terminal 100 is guided so as to be connected to a network in which only a security measure such as application of a security patch corresponding to the NG/error result from the security checking can be taken.

Moreover, one example of the second-type PC quarantine system is disclosed in Patent Reference 1 (Japanese Patent Application Laid-open No. 2003-303114). The security protecting system disclosed as the second-type PC quarantine system chiefly includes a USB (Universal Serial Bus) key, a PC, and a Web server. To receive security checking service by using the disclosed security protecting system, a user inserts the USB key into a USB port of a PC. States of an OS installed in the PC are checked by a program to receive security checking service stored in the USB key. Then, the PC accesses a Web server to which information about the states of the installed OS is transferred as results from the security checking.

The Web server stores, in advance, information to be used as a security measure, for example, a security patch. The Web server, when receiving the information about states of the OS from the PC, judges whether or not the OS installed in the PC is in the newest security state. If the information to be used as the security measure against the states of the OS installed in the PC, for example, the security patch stored in the Web server is not yet applied to the OS installed in the PC (that is, the OS is not yet in the newest security state), a guidance for application of the security patch is displayed on the Web. The user applies the security patch according to the guidance displayed on the Web.

In addition, the Patent Reference 1 also describes that the Web server judges whether the information about the OS to be received by the Web server coincides (or does not coincide) with information about the OS installed on a user's PC being managed by the Web server and, if no coincidence occurs between the information, the information about the OS installed on the user's PC being managed by the Web server is replaced with new information about the OS received by the Web server. Then, a safe set file corresponding to the updated information about the OS for which security measures have been taken is downloaded into the user's PC which ensures the security of the PC.

In the conventional first-type terminal security checking service providing system described above, installation of the dedicated client software is a technological requirement. As a result, in a situation where an access point of the Internet provided by various providers outside a specified organization, for example, in public places is to be used, to provide the security checking service causes a hitch easily. For example, in the case where a system to be used varies from one organization or one provider to another, if tasks that extend over more than one organization are to be performed or a plurality of providers is to be accessed, it is made necessary to install dedicated client software that can correspond to each system.

Moreover, in the case when operations are performed at a cooperative partner, installation of licensed client software must be performed after acquiring a license for a dedicated client software of a system introduced by the cooperative partner and, therefore, a difficult problem of who bears the license fee arises. Another problem is that, since the installation of dedicated client software takes much time and efforts and thorough uninstalling of the dedicated client software after the termination of the cooperative tasks is difficult, it is necessary that a new terminal for cooperative tasks is additionally prepared, which is costly.

In the conventional second-type terminal security checking providing system described above, there arises no technological problem caused by the installation of dedicated client software on a terminal. However, there is a limit to what can be checked by the security checking providing system, that is, the second-type terminal security checking providing system is not yet in a stage where service of providing a security patch or a like is made to be concrete and, therefore, a technological problem of insufficient provision of security measures needed by a terminal remains unsolved.

These technological problems can be solved to some extent by the security protecting system disclosed in the Patent Reference 1 in which the technology provided by the security protecting system is effective as the security measure, however, the security protecting system is lacking in the means that can update information to be used as security measures and in the technology that can make the security measure means shareable among users.

In addition to the above, in the security protecting system disclosed in the Patent Reference 1, both its security checking service providing section and its network connection processing section to be driven according to security check results operate in a direct ganged manner, that is, there is a strong dependent relationship in the connection between the security checking service providing section and network connection processing section and, therefore, the security protecting system is lacking in the technological unit to achieve the system operation in close liaison with the security checking service providing section and with other network managing sections and maintenance of such the network connection managing section is a burden to users.

First Embodiment

FIG. 1 is a block diagram showing configurations of a terminal security checking service providing system according to a first embodiment of the present invention. FIG. 2 is a block diagram showing, in detail, configurations of the terminal security checking service providing system according to the first embodiment. FIG. 3 is a block diagram explaining processes of security checking by the terminal security checking service providing system of the first embodiment. FIG. 4 is a diagram explaining processes of initialization of the terminal security checking service providing system of the first embodiment. FIG. 5 is a block diagram explaining judging processes of connectability of the terminal security checking service providing system according to the first embodiment.

In the terminal security checking service providing system 1, information about objects on which a security check is to be made in a terminal is collected by inserting an external medium that stores security checking client (program) into the terminal and information to be used as security measures stored in the external medium is updated, when necessary, according to results from security checking of the information of the terminal to ensure security of the terminal by using the information to be used as security measures and results from the security checking are input to a network connection managing system by flexibly connected inputting unit. The terminal security checking service providing system 1, as shown in FIGS. 1 to 5, includes terminal 10-i (i=1, 2, . . . , M), external medium 20-j (i=1, 2, . . . , N), an external medium initializing unit 30, a security checking server 40, a network 50, a network connection managing system 70, and a network 80.

The terminal 10-i and the security checking server 40 can communicate with one another over the network 50. The external medium initializing unit 30 is connected to the security checking server 40 over the network 50 or directly by a cable. The network connection managing system 70 is connected to the network 80 to which a user of the terminal 10-i belongs as a subscriber. The network 50 may or may not be connected to the network 80.

The terminal 10-i, external medium 20-j, and external medium initializing unit 30 are placed in a security checking room 90 set up in a corner of a building, lounge at an airport, or public place such as an Internet coffee shop. The external medium 20-j is a processing unit having a connecting terminal, which includes a storing device to store security checking client software (hereinafter simply “security check client”), information to be used as security measures (for example, a security patch), or a like.

The external medium 20-j, as shown in FIGS. 1 to 5, includes a security check client 21-j, a security measure caching unit 22-j, a security check result storing unit 23-j. The external medium 20-j has the same configurations and, therefore, a detailed configuration of the external medium 20-1 is described by referring to FIG. 2. The security check client 21-1, as shown in FIG. 2, is automatically run when the external medium 20-1 is inserted into (connected to) the terminal 10-1 and a connecting terminal of the external medium 20-1 is connected to a connecting terminal of the terminal 10-1 and collects information of the terminal 10-1 of which a security check is to be made and transmits the collected information to the security checking server 40.

The security measure caching unit 22-1 is a unit to receive data (information to be used as security measures) such as a security patch required for taking the security measure with timing when connection is established between a connecting terminal of the external medium 20-1 and that of the external medium initializing unit 30 by inserting the external medium 20-1 into the external medium initializing unit 30.

The security check result storing unit 23-1 is a unit to receive and store security check results received from the security checking server 40 after the security check of the terminal 10-1 to be made by the security checking server 40 is completed.

The external medium initializing unit 30 has a connecting terminal to be connected to the connecting terminal of the external medium 20-1 which is used to connect the external medium initializing unit 30 to the external medium 20-1 and initializes the external medium 20-1 by using the information to be used as security measures fed from the security checking server 40. The external medium initializing unit 30 includes an external medium connecting unit 31 and an external medium data updating unit 32.

The external medium connecting unit 31 is a unit to connect the external medium 20-1 to the external medium initializing unit 30 and to check whether or not the external medium 20-1 is connected exactly. The external medium data updating unit 32 is a unit to write data (information to be used as security measures) such as a security patch required to take security measures or a like to the external medium 20-1 with the external medium 20-1 being connected to the external medium initializing unit 30.

The security checking server 40 includes a security checking unit 41, a security check result storing unit 42, an external medium initializing unit communicating unit 43, a security policy storing unit 44, and a security patch information storing unit 45.

The security checking unit 41 is a unit to make a security check of the terminal 10-i according to information collected by the terminal 10-i and transmitted to the security checking server 40 and to a security checking policy stored in the security policy storing unit 44.

The security check result storing unit 42 is a unit to store security check results, after completion of the security checking by the security checking unit 41, into the security check result storing unit 42 itself or into a security check result database 60 which operates in liaison with the security checking server 40.

The external medium initializing unit communicating unit 43 is a unit to communicate with the external medium initializing unit 30 and to transfer updated information through the external medium data updating unit 32 to the external medium 20-1 to initialize the external medium 20-1, with the external medium 20-1 being connected to the external medium initializing unit 30 and with timing when security checking is made by the security checking unit 41 and, as a result, the security patch information storing unit 45 is initialized.

The network connection managing system 70 includes a security check result obtaining unit 71, a network connectability judging unit 72, and a connectability condition storing unit 73. The security check result obtaining unit 71 is a unit to obtain security check results of the terminal 10-i directly from the terminal 10-i or from the security check result database 60 when the terminal 10-i is to be connected to the network 50. The network connectability judging unit 72 judges whether or not a permission of connection to a network is to be given to the terminal 10-i by checking the security check results against connectability conditions stored in the connectability condition storing unit 73 after obtaining security check results of the terminal 10-i via the security check result obtaining unit 71, that is, an API (Application Programming Interface) and to do switching between the networks 50 and 80.

Next, operations of the terminal security checking service providing system 1 of the first embodiment are described by referring to FIGS. 1 to 5. To receive service of the terminal security checking service providing system 1 of the first embodiment, the terminal 10-i is brought into the security checking room 90 and the prepared external medium 20-j is connected to the terminal 10-i (see A1 in FIG. 3) By this connection, the security check client 21-j (security checking software) stored in the external medium 20-j are automatically run and the information about the terminal 10-i of which a security check is to be made is collected and the collected information is transmitted through the network 50 to the security checking server 40 and a security check of the collected information is made by the security checking unit 41 in the security checking server 40 according to a security policy.

If the security patch to be applied to a security hole found through the security checking proves to be insufficient as a result of the security checking, necessary security measures are provided from the external medium 20-j to the terminal 10-i (see A3 in FIG. 3). Then, the security check results are written from the security checking server 40 through the network 50 into the terminal 10-i and the external medium 20-j (see A4 in FIG. 3).

Next, when the external medium 20-j is inserted into (connected to) the external medium initializing unit 30 (see B1 in FIG. 4), the security check results are transmitted from the external medium 20-j to the security checking server 40 (B2 and B3 in FIG. 4) and are stored in the security check result storing unit 42 and then in the security check result database 60 (see B4 in FIG. 4). As a result, the security checking unit 41 in the security checking server 40 initializes the security patch information storing unit 45 in response to the security check results stored in the security check result storing unit 42 and, with timing of the initialization, contents registered on the security measure caching unit 22 are initialized (written) by using the updated information to be used as security measures (for example, security patch information) via the external medium initializing unit communicating unit 43 and the external medium data updating unit 32 and the security check results stored in the security check result storing unit 23-j in the external medium 20-j are erased and the security check result storing unit 23-j is initialized (B5 and B6 in FIG. 4). The updated contents registered on the security measure caching unit 22 are used as the security measure for the terminal 10-i when the external medium 20-j is again connected to the terminal 10-i.

As described above, when the terminal 10-i provided with security check results is to be connected, when necessary, to the network 80 to which a user's PC is linked, the security check results of the terminal 10-i are fed to the network connection managing system 70 via the security check result obtaining unit 71 of the network connection managing system 70 (see C1 in FIG. 5) or when the terminal 10-i is to be connected to the network 80, the security check results of the terminal 10-i are fed from the security check result database 60 via the security check result obtaining unit 71 to the network connection managing system 70 (see C2 in FIG. 5).

The network connectability judging unit 72, after having obtained the security check results via the security check result obtaining unit 71 (API to interpret the security check results), checks the obtained security results against connectability conditions stored in the connectability condition storing unit 73 to judge whether or not a permission of connection is to be given to the terminal 10-i. If the connection is permitted, switching between the networks 50 and 80 is done.

Moreover, after such the security check as described above, if a security check of the terminal 10-i is again to be made in the security checking room 90, the security checking server 40 checks present states of the terminal 10-i against the previous security check results to judge whether or not another security check is to be made. When the security check is again made and the security patch information storing unit 45 in the security checking server 40 is initialized, contents stored in the security measure caching unit 22-j in the external medium 20-j are updated, through the external medium data updating unit 32, so as to correspond to the initialization of the security patch information storing unit 45.

Thus, according to the configurations employed in the first embodiment, information to be used as security measures stored in the external medium to be applied to a given terminal out of a plurality of terminals is updated according to security check results of the given terminal and, therefore, even if the external medium is being used by other users in a state where the external medium is shared among users, irrespective of the shared use of the external medium, highly improved security of the given terminal can be ensured. Furthermore, the first system in which a security check of a terminal is made is separated from the second system in which a network connection management is performed so that security check results of the terminals can be referred to by using the API and, therefore, the second system corresponding to the reference results by the API can be easily selected even after construction of the entire terminal security checking service providing system, which provides flexibility to the system configurations and, as a result, the terminal security checking service providing system is excellent in expandability.

Second Embodiment

FIG. 6 is a block diagram showing configurations of a terminal security checking service providing system according to the second embodiment of the present invention. FIG. 7 is a block diagram explaining operations of the terminal security checking service providing system according to the second embodiment. Configurations of the second embodiment differ greatly from those of the first embodiment in that a connectability condition, security patch, and security check policy are provided as operating service to achieve up-to-date security measures.

That is, in the terminal security checking service providing system 1A of the second embodiment, a security condition distributing server (hereinafter simply a “policy distributing server”) 110 through a network (Internet) 100 to the network 80. The policy distributing server 110 produces a security policy such as security patch information, connectability condition data, security check policy, or a like to store the produced security policy on the policy distributing server 110, with timing when security conditions have been changed, for example, with timing when a security patch or virus check software has been updated. Moreover, a network connection managing system 70 is so configured as to be communicable through the networks 80 and 100 to the policy distributing server 110 periodically or nonperiodically in case of emergency and as to be able to distribute the information obtained by the communication to a security policy storing unit 44, security patch information storing unit 45, and connectability condition storing unit 73. Configurations other than above in the second embodiment are the same as those in the first embodiment and same reference numbers are assigned to parts having the same functions as in the first embodiment and their descriptions are omitted accordingly.

Third Embodiment

FIG. 8 is a diagram schematically showing configurations of a terminal security checking service providing system 1B of the third embodiment of the present invention. FIG. 9 is a diagram explaining operations of the terminal security checking service providing system according to the third embodiment. Configurations of the third embodiment differ greatly from those of the first embodiment in that advertisements can be distributed for latency time during which security checking service is being provided.

That is, in the terminal security checking service providing system 1B of the third embodiment, as shown in FIG. 8, a characterizing portion of the third embodiment is that an advertisement distributing server 120 is connected to the network linked to the terminal security checking service providing system 1 shown in FIG. 1. The advertisement distributing server 120 distributes advertisements to the terminal 10-i while a security check of the terminal 10-i is being made by the security check server 40 on the Internet 50. Configurations other than described above are the same as those in the first embodiment and same reference numbers are assigned to parts having the same functions as in the first embodiment and their descriptions are omitted accordingly.

Next, operations of the terminal security checking service providing system 1B are described by referring to FIGS. 8 and 7. Operations other than those of the advertisement distributing server 120 to be described below are the same as those in the first embodiment and their descriptions are omitted accordingly. In the terminal security checking service providing system 1B, a security check of the terminal 10-i is started by the security check server 40. The security check processing to be performed among the external medium 20-j, terminal 10-i, and security checking server 40 is the same as those in the first embodiment (the processing A1, A2, and A3 in FIG. 9 are the same as A1, A2 and A3 in FIG. 3).

For latency time during which the security check is being made, the advertisement distributing server 120 being connected through the network 50 to the terminals 10-i distributes advertisements to the terminal 10-i (A5 in FIG. 9). When the above security check is completed, security check results are written into the terminal 10-i and external medium 20-j (see A4 in FIG. 9).

Thus, according to configurations of the terminal security checking service providing system of the third embodiment, for latency time during which the security check of the terminal is being made, advertisements can be distributed from the advertisement distributing server, over the network, to the terminal and, therefore, a provider of security checking service, by operating the system in liaison with a sponsor of the advertisement, can provide more cost-effective service.

It is apparent that the present invention is not limited to the above embodiments but may be changed and modified without departing from the scope and spirit of the invention. For example, the terminal security checking service providing system of the present invention may be so configured that the advertisement distributing server employed in the third embodiment is embedded in the system of the second embodiment.

In the above embodiments, when one or more external media are employed for security checking of one or more terminals, security check results used for identification and authentication of each terminal are transferred from the one or more terminals to one or more external media and security measure information corresponding to the security check results are sent back to the security checking server, one or more external media, and one or more terminals. However, when the information about a terminal of which a security check is to be made is transferred from the terminal to the security check server, the information used for identification and authentication of the terminal may be transferred to the security check server and, after completion of the security checking by the security check server, security measures corresponding to security check results held by the security check server may be sent back to the terminal corresponding to the information about the identification and authentication to be used for ensuring security of the terminal. In addition, the advertisement distributing server described in the third embodiment may be embedded in the above modified configurations of the terminal security checking service providing system of the present invention.

Moreover, in the above configurations, the security condition (policy condition) described in the second embodiment may be distributed from the policy distributing server to the security checking server and the network connection managing system.
